UNITED STATES PATENT CIGAR BUNCH TR MMER Constantin Friedrich Riiber, Dresden, Germany,

assignor to Universelle Cigarettenmaschinenfabrik J. C. Mueller & 00., Dresden, Germany Application August 20, 1935, Serial No. 36,944 In Germany August 2'7, 1934 8 Claims. (o1. ii-s9) The present invention relates to means for smoothing the mouth piece ends of cigar fillers, and has for an object to provide a method and apparatus for accomplishing this purpose, so that the mouth piece ends of the fillers when delivered from the press and ready to receive the wrappers will be smooth and even so that the wrappers may be properly applied.

It is well known in the art that cigar 'fillers with the wrappers thereon are introduced into a press or mold out of which the rolled up ends of the wrapper protrude at opposite sides, particularly at the mouth piece end of the filler. Before the filler is introduced into'the press or mold and before the wrapper is applied thereto the filler is clipped at its ends to remove protruding portions. 7 r

In this operation'a ridge or projection remains upon the mouth piece end of the cigar and this projection prevents the smooth application of a thin or delicate wrapper. To remove this ridge or projection it is customary to squeeze the clipped (and 'of the filler into a socket having the shape' of the cigar point and, by turning, to smooth out the end of the filler and thereby eliminate the ridge. 1 a

3 It has been found in practice that such smooth- 7 ing out of the ridge onthe end of the filler is not satisfactory because it does not absolutely remove the ridge and the same swells or rises from'the surface of the cigar point.

To overcome this difficulty is an object of the invention, and means is therefore provided for actually grinding or cutting away this ridge or projection so as to completely remove the ridge and not'merely press it back into the body of the j cigar.

It is known that means have heretofore been provided for the removal of the compressed edges at the ends of the cigar fillers with the use of a socket receiving the end of the filler to be treated and in which the socket is cut off obliquely to the longitudinal axis of the filler directly in front of a cutting surface such as a rotating wing knife.

Howeven'the cigar filler has to be turned by hand in the socket and the operation is somewhat in the nature of the well known pencil sharpener. The present invention provides means for overcoming the difiiculties encountered with this con- Y struction and operation andbysomounting and operating a cutting implement that it will encircle the mouth picce end of the filler and automatically, remove the ridge or projection left by the clipping of the wrapper.

' With the foregoing and other objects in view,

the invention will be more fully described here;

inafter, and will be more particularly pointed out and showing parts in section taken on line 2-2 of Fig. 1, and

Figure 3 is a detail fragmentary view of the mouth piece end of the filler showing in dotted lines the twisted end of the wrapper before clipping and showing a cutter in its relative position thereto. a

With reference first to Figure 3, a cigar filler W is shown whichhas been worked into shape in tlg usual manner in the shaping press and which shows in full lines the'filler after being clipped at its mouth piece end. The rolled up portion of the wrapper; prior to clipping is shown at T and this is the portion which is clipped from the end of the filler. When this portion T is clipped from the filler there'remains an annular ridge or-proje'ction G which is adapted to beremoved by the present invention and by use of a cutter 8. The

cigar fil1er W is held fast while the ridge G is removed. The cutter 8 works against the cigar filler W and is carried around the cigar filler W in the path of the ridge or projection G to remove it by the independent operation of the cutter.

This-operation may be carried out in various ways andin Figures 1 and 2 there is shown a preferred type of apparatus or device for accomplishing this result.

Referring now to Figures 1 and 2, a drive shaft I is connected by gears 2 and 3 to a spindle 4 which is mounted in a suitable bearing ii of the machine frame. The upper endof the spindle 4 is provided with a socket ii shaped to the mouth piece end of the cigar filler W. At oneside'f of the vertical axis of the socket 6, the latter is provided with an opening to. andat one side of .the

adjacent portion of the'spi'ndle t is disposed a "horizontal shaft 1 which carries a mil ling cutterB' contact the same for removal of the ridgeor V projectioniG. The shaft 1 is mounted in a bracket bearing'B which rises from the body ill: of the bracket disposed at one side of the spindle 4, and

the shaft I carries at its outer end a bevel gear wheel II which meshes with a second bevel gear wheel I2 carried on the offset vertical shaft I3.

The shaft I3 is mounted. in a bearing I4 carried by the body bracket It. The body bracket I0 is secured to the axle 4 by a pair of spaced ears l5 embracing the shaft 4 and which are adapted to be clamped on the shaft by a set screw I6 or the like as shown.

The body bracket I0 thus turns with the shaft about the axis of the latter and carries with it the shafts I3 and 1 so that the milling cutter 8 is maintained at all times in the opening 6a of the socket 6 as the latter turns and smooths the mouth piece end of the cigar filler W.

Mounted on the lower end of the offset shaft I3 is a planetary gear wheel or pinion I I which meshes with a sun gear l8, the latter being supported to turn about the shaft 4 upon a collar 4a.

or the like, and the sun gear [8 being held against rotation by an anchoring arm 29 secured by a screw l9 or the like to the sun gear I8 and. which has an arm extending downwardly and mounted for vertical sliding movement in one side of the main bearing 5 of the machine frame. The spindle 4 is adapted to move vertically in the hearing 5 and the anchoring bracket 20 is adapted to move therewith. The lower end portion of the spindle 4 is provided with a key or spline 2| which engages the hub of the gear 3 so that the spindle 4 may be driven by the gear 3 at all times and the spindle 4 may be slid downwardly through the gear 3.

Upon the lower extremity of the spindle 4 is disposed a shifting collar 22 provided with an annular groove 23 for the reception of a fork 24 or other suitable device used in the shifting of shafts or the like so that the collar 22 with the spindle 4 may be moved from the solid to the dotted line position shown in Figure 1. The parts on the upper end of the spindle 4 are moved correspondingly so as to grip the tip or mouth piece end of the cigar fillerW.

In operation of the machine, the drive shaft I turns the spindle and the latter swings the body bracket Ill-thereabout while the sun gear I8 remains stationary with the main bearing 5 and consequently the shafts I3 and I are rotated so that the milling cutter 8 is turned to trim off the annular projection or ridge G on the mouth piece end of the cigar. The cigar filler W, the cigar filler, is held stationary while the socket 6 slides thereabout and suitably shapes the mouth piece and admits of the removal of the ridge.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such change-s and modifications being restricted only by the scope of the following claims.
